My husband and I are big fans of zucchini. Our typical breakfast includes fried zucchini, lots of it, with mushrooms, onions and eggs. Naturally, zucchini plays a big role in my garden. I have tried for many years to get zucchini to grow consistently and well. It is not as easy as I thought it would be but this is the second year now we have been enjoying early and great abundant zucchini. So I think I have the knack of it now.

As my followers will recall, we live in Manitoba near the 51st parallel and so we have to adjust our gardening for late and early seasons frosts and occasionally even snow in May. Zucchini are delicate when it comes to frost, and slugs and cutworms love to eat them. After trying for years to get really good zucchini, I finally gave up on growing them in the garden and I switched to container gardening. This way, on nice spring days we can put the plants outside but if we have one of our late May frosts (or even snows) they can be carried inside to warm safety until the cold passes.

Since they are going into containers anyway, it makes sense to start them indoors under artificial lights. I started mine April 15th this year from seed I saved from the previous year’s harvest. I had both yellow and green (actually called “midnight” variety) that grew very well for me. Since we like to eat our zucchini young, that meant leaving some to grow large enough to produce mature seeds. That happened more towards the end of the season when we had so much I was actually getting sick of it.

The zucchini grow quickly. In this image they are only about three and a half weeks old. The tiny tomato plants beside them were started at the same time. Zucchini like rich soil, and they require a lot of water but they also like good drainage. This is why some successful gardeners put them on hills in the garden. I started mine out in high quality potting soil. Zucchini are subject to blossom rot (like tomatoes) so I added extra calcium powder and ground egg shells to the soil. Deeper pots work better in the early stages as the zucchini like to set deep roots fast. Zucchini also like to grow with companions so I start with about six seeds per pot and then reduce it down to two plants per pot once the first leaves are open.

Zucchini also need abundant sunshine and so as soon as possible I put them outside in my little greenhouse. At about six weeks, I repotted them into some large pots I scrounged from the local dump that were originally used for transporting trees, again using the best quality potting soil with water conserving beads and fertilizer. (Pot size is 12 inches (30cm) around and 10 inches (24cm) deep.) I topped up the calcium in the bigger pots as well. I started with six pots going. Four are yellow and two are green. I gave one to my neighbour who has also had trouble getting good zucchini in the past.

Another advantage to getting the plants outside well before it is warm enough for the garden is to let pollinators get at the blossoms. My plants had blossoms by when they went into the big pots at 6-7 weeks and they were soon full of busy bees, especially bumble bees. The plants grew and overflowed the edges of their pots. By June I didn’t have to worry about carrying them inside overnight. I moved them into their own sunny location in the back part of the lawn. The nearby trees provide shelter from the occasionally fierce prairie wind and they are near the rain barrel. Even in these pots they need watering almost every day. They do much better with soft rain water than our extremely hard iron laden tap water.

It is important to pick the zucchini young in order to keep the plant producing more. Last year I noted that the zucchini ran roots out of the pot into the ground and seemed to halt growing for a few days when I moved them. So once they are in their place on the lawn I now try to mow around the pots rather than move the pots to mow. My final tip is that as soon as the first two plants are producing zucchini, put in more seeds near the edges. Allow two of these secondary plantings to reach maturity for a total of four plants per pot. The second pair of plants will take over peak production just as the first set are getting too old.

And we are now enjoying the rewards of my not-too-hard work. It is more about planning than work. I picked my first zucchini last week which is nine weeks after I planted the seeds. Yesterday I harvested four good sized zucchini. Two are yellow and two are green. One of the green ones I made into a layered zucchini vegetable lasagna. (Cooking tip; zucchini have a lot of moisture so I find you need to double the typical cooking time fora lasagna and leave the lid off for the last half of the cooking to make a good texture that is not watery.) The other three are in my fridge and will be consumed soon.
